Product details
The ECS-147.4-20-1X by ECS Inc. revolutionizes Crystals technology for aerospace applications, featuring radiation-hardened design and exceptional phase noise performance. Developed for satellite communication systems, this component ensures precise timing in the most demanding space environments while maintaining signal integrity across wide temperature fluctuations.Engineered as a MHz Crystal, this oscillator demonstrates superior resistance to single-event effects compared to commercial-grade alternatives, critical for navigation and telemetry systems.Operating at 14.7456 MHz, the device provides stable clock references for phased array antennas and onboard data processing units in LEO satellites.With ±50ppm stability, it maintains synchronization accuracy during orbital thermal cycling, from eclipse transitions to direct solar exposure.The ±30ppm tolerance specification meets stringent requirements for deep space probe timing subsystems and interplanetary communication.Optimized with 20pF load capacitance, it minimizes power consumption while ensuring reliable start-up in vacuum conditions.The radiation-tolerant 25 Ohms ESR characteristic preserves signal quality despite cosmic ray exposure in GEO satellite applications.Utilizing Fundamental technology, it achieves the necessary spectral purity for synthetic aperture radar payloads and scientific instruments.Rated for -10°C ~ 70°C, the component withstands the extreme thermal variations encountered during launch and orbital operations.The Through Hole configuration incorporates hermetic sealing to prevent outgassing in space vacuum environments.Housed in a HC-49/U package, it meets NASA outgassing standards while providing mechanical stability during rocket vibration profiles.With 0.447" L x 0.183" W (11.35mm x 4.65mm) dimensions, the compact design enables high-density integration in cubesat and smallsat avionics.The 0.530" (13.46mm) low profile accommodates strict form factor requirements in satellite payload modules.
